EDWIN C. DIGKINSON, OF TALCOTT, WEST VIRGINIA.

GAS-BURNER.

Specicaton of Letters Patent.

Application led May 3, 1911.

Patented Apr. 30, 1912.

Serial No. 624,687.

To all whom t may concern Be it known that I, EDWIN C. DICKINSON, acitizen of the United States, residing at Talcott, in the county ofSummers and State of West Virginia, have invented new and usefulImprovements in Gras-Burners, of which the following is a specification.

This invention relates to certain novel and useful improvements in gasburners.

In carrying out my invention, it is my purpose to provide an improvedgas burner which may be used in conjunction with gas fixtures for eitherartificial or natural gas.

A further object of the invention is to provide a valve, suitablylocated in the gas supply pipe leading to the burner, said valve havingconnections with a thermostatic rod arranged within the burner, wherebysaid valve will open and close responsive to the expansion andcontraction of the rod.

A further object of my invention is to providea simple, reliable andeiiicient form of device for thermostatically controlling the openingand closing of the valve within the supply pipe, whereby said valve willbe automatically closed when the light has been extinguished, therebyobviating the liability of gas accidentally escaping from theburner.

With the above-recited objects and others of a similar nature in view,the invention consists in the construction, combination and arrangementof parts set forth in and falling within the scope of the appendedclaims.

In the accompanying drawings :-'-Figure 1 is a view in side elevation ofa gas burner embodying my invention, the gas mantle and support thereforbeing shown in dotted lines. Fig. 2 is a top plan view of the burner.Fig. 3 is a vertical sectional view. Fig. 4 is a cross sectional view,taken on the line 4-4 of Fig. 3. Fig. 5 is a similar view, taken on theline 5-5 of Fig. 3. Fig. 6 is a cross sectional view taken on the line6-6 of Fig. 1. j

Referring now to the accompanying drawings in detail, the numeral lindicates a `supply pipe adapted to be threaded at its end 2 into a gasfixture of any suitable character, the opposite end of said -pipe beingconnected to the elbow 8, said elbow also having threaded therein thevertical tube 4, forming part of the gasV burner proper. This verticaltube is provided intermediate its length with a horizontal partition 5having a perforation or opening 6 for the passage of gas, said openingbeing controlled by a pivoted plate or slide 7 having graduatedperforations 8 arranged therein and designed to be brought intoalinement with the opening in the partition to regulate the amount ofgas admitted to the mixing chamber. This tube is also formed above thepartition with air inlet slots 9, designed to register with similarslots 10 formed in the upper tubing 11, which is sleeved or telescopedover the end of the tube 4.

The numeral 12 indicates a rotary collar having the under side 13, openfor the admission of air to the mixing chamber, which chamber is formedby the tubes above the partitions 5 and is indicated by the letter m.This rotary collar is formed with vertical stops 14 between which theend of the pivoted plate or slide projects, whereby said collar whenrotated will move said slide to bring the desired opening thereof intoalinement with the opening in the diaphragm. As this method ofregulating the amount of vair and gas admitted to the mixing chamber isold and well-known in the art, I lay no claim to the same. The upper ortelescoping tube 11 is formed at-its lower end with a circumferentialflange 15, which is spaced apart from a similar flange 16 carried by thetube 4, the screws 17 connecting the tubes at the flanges, each ofscrews being surrounded by a coiled spring 18, designed to tension theupper tube, the latter having a certain amount of movement relative tothe tube 4, the upward movement of the telescoping tube being limited bythe head of the screws 17.

The thermostatic control regulating device for the burner is best shownin Fig. 3, wherein the numeral 19 designates a block located within thesupply pipe and having a gas port or passage therein, which is injdicated at 20, said port being controlled by the beveled valve 21,carried by the rod 22 which latter is fulcrumed or pivoted at 23 to theblock 24, the end of said rod extending into vthe elbow 3 and ispivotally `connected at 25 to the thermostat rod 26, which latterextends vertically upward through the mixing chamber of the burner, therod being threaded at 27 in the ring spider 28 at the top of thetelescoping tube 11, the upper end of said thermostat projecting intothe mantle attachment as shown at 29 in Fig. 1. The mantle attachment isdesignated by the letter X, but as this mantle and its support isV of awell-known type, and forms no part of the present invention it need notbe described in detail.

From the above description taken in connection with the drawings theconstruction and operation of my improved burner will be readilyapparent. The usual gas cock is turned to permit the llow of gas throughthe channeled or bored block, and into the supply pipe, the telescopingsleeve being pressed downward momentarily to permit this. The gas isthen lighted, and as the thermostatic rod becomes heated so that itexpands, and in such expansion presses down against the lever rod 22 atthe end 25 thereby elevating the valve 2l from the month of the passage20, thus permitting the gas to flow through the burner to the mixingchamber and point of ignition. So long as the gas is lighted, the rodwill be heated and the valve elevated from its seat in the block.2l/Then the gas is turned off the rod cools and contracts, and the valvedrops back into closing position.

It will be noted that I have provided a safe, eliicient and simple meansfor insuring that no gas will escape from the burner when the light isextinguished, and furthermore my invention is applicable to any type ofburner, either for natural or artificial gas.

While I have herein shown and described one particular embodiment of myinvention, by way of illustration, I wish it to be understood that I donot confine myself to all the precise details of construction herein setforth, as modification and variation may be made without departing fromthe spirit of the invention or exceeding the scope of the appendedclaims.

lVhat I claim is l. The combination with a gas supply pipe, of a burnerconnected thereto and including a tube, and a sleeve telescoping oversaid tube, a mixing chamber for air and gas formed by the sleeve andtube, a resilient connection between the sleeve and tube, a rod pivotedin the supply pipe, a valve carried at the end of said rod andcontrolling the gas channel to the supply pipe, a thermostatic rodextending through the burner and pivoted at its lower end to thefirst-men tioned rod, the construction and arrangement being such thatthe valve is elevated to permit gas to enter the supply pipe when therod is expanded by the heat from the burner, said valve being closedupon the contraction of the rod.

2. The combination with a supply pipe, a channeled block located in thesupply pipe, a rod pivoted in the supply pipe, a valve formed integralwith the rod at one end thereof and closing the channel in the block, agas burner connected to said supply pipe and comprising a stationarytube, a sleeve sliding on said tube, a resilient connection between thesleeve and tube, a diaphragm in the tube having an opening for the flowof gas therethrough, said tube and sleeve having alining openings forthe admission of air, and resilient connections between the sleeve andtube, a metallic rod extending through the tubes and connected intermediate its length to the sliding sleeve near the top of the latter andconnected at its lower end to the valve carrying rod, the constructionand arrangement being such that said valve is open when the rod isexpanded by the heat of the burner, and closed when said rod contracts.

In testimony whereof I affix my signature in presence of two witnesses.
